Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to perform positioning determination procedures, such as angle-based positioning procedures, with a base station to determine the position of the UE relative to the base station. To avoid positioning ambiguities that may result from antenna element spacing of an antenna module of the UE at some frequencies, such as mutual coupling or grating lobes, a UE may transmit a capability message indicating the capability of the UE related to the positioning procedures. In some cases, the UE may de-activate one or more antenna elements to increase the spacing between the antenna elements so as to mitigate mutual coupling when transmitting or receiving positioning reference signals. In some cases, the UE may request that the positioning reference signals be scheduled on some frequencies, not scheduled on other frequencies, or both.

The method includes: determining configuration information of a positioning reference signal of a positioning vehicle; and transmitting, according to the configuration information, the positioning reference signal to a vehicle to be positioned, and the vehicle to be positioned determines a positioning measurement quantity based on the positioning reference signal. The configuration information of the positioning reference signal is determined by the positioning vehicle and the transmission of the positioning reference signal is started to the vehicle to be positioned according to the configuration information, and the vehicle to be positioned can determine the positioning measurement quantity according to the positioning reference signal, and improving the positioning performance and avoiding configuration conflicts between positioning reference signals.

In an aspect, a first network node may receive, from a second network node, one or more reference signals transmitted using one or more first polarizations known to the first network node, wherein the one or more reference signals are received having one or more second polarizations. The first network node may determine whether the one or more reference signals followed a line-of-sight (LOS) path between the first network node and the second network node based on a comparison of signal characteristics related to the one or more first polarizations and signal characteristics related to the one or more second polarizations.

A positioning node determines a muting configuration used by one or more base stations for controlling muting of positioning reference signals. The positioning reference signals are transmitted at recurring positioning occasions from the one or more base stations to radio equipment in a wireless communication network. The muting configuration is determined from signaling received from the one or more base stations. The positioning node sends the muting configuration information as higher-layer signaling for receipt by the radio equipment receiving the positioning reference signals. The muting configuration information includes a muting occasion parameter indicating positioning occasions to which muting applies, and each of the positioning occasions comprise two or more consecutive subframes that repeat at a predetermined periodicity.

Localization systems and methods for transmitting timestampable localization signals from anchors according to one or more transmission schedules. The transmission schedules may be generated and updated to achieve desired positioning performance. For example, one or more anchors may transmit localization signals at a different rate than other anchors, the anchor transmission order can be changed, and the signals can partially overlap. In addition, different transmission parameters may be used to transmit two localization signals at the same time without interference. A self-localizing apparatus is able to receive the localization signals and determine its position. The self-localizing apparatus may have a configurable receiver that can select to receive one of multiple available localization signals. The self-localizing apparatuses may have a pair of receivers able to receive two localization signals at the same time. A bridge anchor may be provided to enable a self-localizing apparatus to seamlessly transition between two localization systems.

In the technical solution, a mobile terminal meeting anchor point requirements is taken as a beacon terminal to provide convenient positioning services, so as to avoid deployment and maintenance of a large number of beacons, hardware of routers, and related mapping relationship, thus greatly reducing investment costs and facilitating promotion of use.
